Renewable capacity now comprises about a quarter of total global power-generating capacity and supplies close to 20% of global electricity, with most of this provided by hydropower.

In 2010, renewable energy supplied an estimated 16% of global final energy consumption and delivered close to 20% of global electricity.

The top five countries for non-hydro renewable power capacity were the United States, China, Germany, Spain, and India.

Global solar PV production and markets more than doubled in comparison with 2009, thanks to government incentive programmes and the continued fall in PV module prices.

Germany installed more PV in 2010 than the entire world added in 2009.

PV markets in Japan and the U.S. almost doubled relative to 2009.

Globally, wind power added the most new capacity (followed by hydropower and solar PV), but for the first time ever, Europe added more PV than wind capacity.

Renewable energy policies continue to be the main driver behind renewable energy growth.

Last year, investment reached a record $211 billion in renewables -- about one-third more than the $160 billion invested in 2009, and more than five times the amount invested in 2004.

Developed countries still led the way in investment in small-scale power projects and R&D during 2010. Germany, Italy and the US were the top three.

China led the world in the installation of wind turbines and solar thermal systems and was the top hydropower producer in 2010. The country added an estimated 29 GW of grid-connected renewable capacity, for a total of 252 GW, an increase of 13% compared with 2009.

Renewables accounted for about 26% of China’s total installed electric capacity in 2010, 18% of generation, and more than 9% of final energy supply.

In the European Union, renewables represented an estimated 41% of newly installed electric capacity. While this share was significantly lower than the more than 60% of new capacity in 2009, more renewable power capacity was added in Europe than ever before.

The EU exceeded all its 2010 targets for wind, solar PV, concentrating solar thermal power, and heating/heat pumps. Countries including Finland, Germany, Spain, and Taiwan raised their targets, and South Africa, Guatemala, and India, among others, introduced new ones.

Developing countries (collectively) have more than half of global renewable energy power.
